Inhad same issue yesterday ,i copy and pasted 8 small parts of a photo each time i had to zoom in so that i could move them which is annoying. Setting a button to on/off enable nodes editing when its off you can easy move small parts.
Thanks
I understand that you just supposed to touch the center of your selection and not the nodes to move the selection. But it is impossible with very tiny objects. I also understand that you can zoom into the object to avoid touching the nodes. That's what I do as suggested by another user. But that is very inconvenient . In some other apps when you use the move tool you can put your finger outside the box and move it.
